The Complete Website Launch Checklist

Launching a website is exciting—but rushing to go live without proper preparation can lead to costly mistakes. Whether you're launching a brand new site or redesigning an existing one, this comprehensive checklist ensures you've covered all the bases before hitting "publish."

Pre-Launch: Content & Functionality

✓ All Content is Finalized and Proofread

Before launch, review every page for:

• Spelling and grammar: Use tools like Grammarly or have someone proofread
• Placeholder text: No "Lorem ipsum" should remain
• Brand consistency: Voice, tone, and terminology are uniform
• Accuracy: Facts, dates, prices, and contact information are current
• Links: All internal and external links work properly

✓ All Images Are Optimized

Large image files slow down your site. Before launch:

• Compress images without losing quality (use tools like TinyPNG or ImageOptim)
• Ensure all images have descriptive alt text for accessibility and SEO
• Use appropriate image formats (WebP for photos, SVG for logos)
• Verify images display correctly on all screen sizes

✓ All Forms Are Working

Test every form on your site:

• Contact forms submit successfully
• Confirmation emails are sent and received
• Form validation works (required fields, email format, etc.)
• Error messages are clear and helpful
• Thank you pages display correctly
• Form submissions are being delivered to the right email/database

✓ Navigation is Intuitive

Test your site's navigation:

• Menu items are logically organized
• Users can find key pages within 2-3 clicks
• Mobile menu works smoothly
• Breadcrumbs are accurate (if applicable)
• Footer links are functional

Technical: Performance & Security

✓ Site Speed is Optimized

Test your site speed using:

• Google PageSpeed Insights: Aim for 90+ on mobile and desktop
• GTmetrix: Check loading time and performance scores
• Pingdom: Test from multiple locations

Common speed optimizations:

• Enable browser caching
• Minify CSS and JavaScript
• Use a Content Delivery Network (CDN)
• Implement lazy loading for images
• Choose quality hosting (avoid bargain shared hosting)

✓ Mobile Responsiveness is Perfect

Test on actual devices (not just browser tools):

• iPhone and Android phones
• Tablets (both orientations)
• Different screen sizes

Verify:

• Text is readable without zooming
• Buttons and links are easily tappable
• Images scale appropriately
• No horizontal scrolling occurs
• Forms are easy to complete on mobile

✓ SSL Certificate is Installed

Your site MUST have HTTPS:

• SSL certificate is properly installed
• All pages redirect from HTTP to HTTPS
• Mixed content warnings are resolved
• Certificate is valid and not expired

Without SSL, browsers will warn visitors that your site is "not secure," destroying trust.

✓ Backups Are Configured

Set up automatic backups:

• Daily backups of your database
• Weekly backups of your files
• Off-site backup storage
• Test that backups can be restored

✓ Security Measures Are in Place

Protect your site from threats:

• Update all software (CMS, plugins, themes)
• Use strong, unique passwords
• Enable two-factor authentication for admin accounts
• Install security plugins (Wordfence, Sucuri, etc.)
• Hide your CMS version
• Disable directory browsing
• Limit login attempts

SEO: Making Sure Google Finds You

✓ SEO Fundamentals Are Covered

Basic on-page SEO for every page:

• Title tags: Unique, descriptive, 50-60 characters
• Meta descriptions: Compelling, 150-160 characters
• Header tags: Proper H1, H2, H3 hierarchy
• URL structure: Clean, descriptive URLs (not "page1.html")
• Internal linking: Pages link to relevant content

✓ Google Search Console is Set Up

Register your site with Google:

• Submit your sitemap.xml
• Verify ownership
• Check for crawl errors
• Monitor search performance

✓ Analytics Are Installed

Set up tracking before launch:

• Install Google Analytics 4
• Set up conversion goals
• Enable e-commerce tracking (if applicable)
• Configure privacy settings (GDPR compliance)
• Test that tracking is working

✓ Sitemap is Generated

Create and submit a sitemap:

• Generate XML sitemap (use plugins or tools)
• Include all important pages
• Exclude admin, thank you, and duplicate pages
• Submit to Google Search Console
• Reference sitemap in robots.txt

✓ Robots.txt is Configured

Control what search engines can access:

• Allow search engines to crawl your site
• Block admin areas and sensitive pages
• Reference your sitemap location
• Test using Google's robots.txt Tester

Browser & Device Testing

✓ Cross-Browser Testing

Test your site in:

• Chrome (most popular)
• Safari (iPhone users)
• Firefox
• Edge

Verify:

• Layout displays correctly
• Features work as expected
• No console errors

✓ Accessibility is Addressed

Make your site usable for everyone:

• All images have alt text
• Color contrast meets WCAG standards
• Forms have proper labels
• Site is keyboard-navigable
• Screen readers can access content

Use tools like WAVE or Lighthouse to test accessibility.

Legal & Compliance

✓ Legal Pages Are Present

Required pages for most websites:

• Privacy Policy: How you collect and use data
• Terms of Service: Rules for using your site
• Cookie Policy: If you use cookies (EU requirement)
• Disclaimer: If providing advice or information

Consult a lawyer to ensure compliance with regulations like GDPR, CCPA, etc.

✓ Cookie Consent is Implemented

If you use cookies (including analytics):

• Display a cookie consent banner
• Allow users to accept/reject
• Document cookie usage in your policy
• Respect user preferences

Pre-Launch Final Checks

✓ Favicon is Uploaded

That little icon in the browser tab:

• Create a 512x512px favicon
• Upload in multiple sizes (16x16, 32x32, 180x180)
• Test in multiple browsers

✓ 404 Page is Customized

Create a helpful 404 error page:

• Brand it to match your site
• Provide navigation back to main pages
• Add a search function
• Keep the tone friendly, not alarming

✓ Contact Information is Correct

Triple-check:

• Email addresses are correct and working
• Phone numbers are accurate
• Physical addresses match Google Maps
• Social media links go to the right profiles

✓ Development Mode is Disabled

Remove anything related to development:

• Remove "noindex" tags from robots meta
• Enable site indexing in CMS settings
• Clear all caches

Post-Launch: Monitoring & Maintenance
